I remember trolling you on a thread on NRDB and asking for some discussion around this ID. Glad it found me here XD Thanks for the post.
Agreed that he is close to, if not, the best early rig builder available. Opus is a cool solution for momentum and you list some great tricks with Workshop and Sol I hadn't thought of.
After reading this I do agree that a complete suite rather than a total focus on ice destruction is a better plan, and currently, sentries are problematic. This is why I veered to the 'stealth' build initially, but the arguments here are convincing. Having said that I'm going to skin it back up, there are some tricks here that will make it much better than I was playing it.
The time is defo right for the new and interesting rather than the tried and tested. I really hope there are some changes and mix ups in the meta cos it is feeling a little stagnant right now.
